A durable, efficient and inexpensive corona discharge ozonator tube assembly of the Siemens Ozonizator. A very high conversion efficiency of 4.0 kWhr/kgO.sub.3 is attained, demonstrating a thermal efficiency of approximately 20%. The assembly consists of industry-standard sized stainless-steel and glass elements held in position by means of a novel nonconductive endcap design. The resulting output ozone concentration of 2.5% at a one liter per minute air flow rate provides approximately 77 grams per day of ozone for the preferred embodiment having a single five-inch long corona chamber.
